UL Approved Voltage Transformers Converters


UL Certification: What does it mean? Why is it important?

Underwriters Laboratories, better known as UL, has existed since 1894 for the express purpose of “promoting safe living and working environments.” UL provides a diverse range of important services, including the establishment of safety and environmental standards, codes, and requirements.

Manufacturers of quality products typically seek UL approval; it means their goods have been tested to meet UL’s benchmarks, and hence are of superior quality. According to UL, the typical American home has an average of 125 products bearing the familiar UL stamp of approval in a visible place. You’ve seen plenty of them, we’re sure.

One place you won’t find the UL stamp is on cheap, Chinese-manufactured voltage converters that are built with inferior components, such as aluminum wire. These products are notorious for catching fire, even exploding, when confronted with wattage and amperage loads they can’t handle. They are pushed out of the factory as quickly and cheaply as is possible, without consideration for the rigorous safety standards that an electrical unit you are placing inside your home should have.

Currently, a handful of ACUPWR transformer/voltage converters, including many of our AD step down models, have met UL approval while the remainder of our line is presently undergoing compliance testing.

Ultimately, having UL approval for all of ACUPWR products further ensures what we already know; you’re getting the safest, best made, most reliable, and most long-lasting voltage converter around…made in the USA, fully inspected, and bench tested at full load before leaving the factory.
